29-Piece Jobber Length Drill Bit Set
This Chicago-Latrobe 69861 set contains twenty-nine high-speed steel drill bits with a 118-degree point angle. It is designed for general-purpose drilling in metal, wood and plastic. The TiN finish adds surface hardness and reduces friction during use. Suitable for maintenance technicians and workshop use.
TiN-coated high-speed steel construction
The machining-grade high-speed steel substrate resists heat buildup when drilling at typical jobber speeds. Titanium nitride coating lowers cutting temperatures and extends edge life in abrasive materials. Standard 118-degree geometry provides reliable centring without a pilot hole. No special coolant or speed restrictions are indicated.
Replaces worn fractional bit assortments
This set upgrades from incomplete or dull collections that slow down repetitive drilling tasks. The jump is worth it when the current bits no longer hold a sharp edge in steel or aluminium. Not for buyers who need metric sizes, reduced-shank bits or specialised point geometries beyond the standard 118-degree profile.

Questions about this item
How do I install the 29 drill bits from the 69861 set into my drill chuck, and what step do people often miss?
Open the chuck jaws wide enough for the largest shank, insert each bit straight so the shank seats fully, then tighten securely; the step many miss is checking that the bit runs true before drilling.
What maintenance or replacement will the 29-piece 118-degree set need over time?
The high-speed steel bits with TiN finish dull with use; sharpen or replace individual bits when cutting edges wear, and wipe them clean after each job to prevent corrosion.
What limit appears first when using the 69861 jobber-length bits continuously in hard material?
Heat buildup at the 118-degree point reduces hardness and cuts tool life; use cutting fluid and peck drilling to manage temperature during sustained work.
